Offered as the world’s smallest combo
chip solution for automotive keyless entry with immobilizer
functions, the NCF2960 integrates a security transponder, micro
RISC kernel, and multi-channel radio transmitter in a single
package. The chip’s package size has been reduced by 44%
compared to the previous generation and is now housed in a 4 x 4
mm, 24-pin HVQFN package.

One of the chip’s key features is its
RF multi-channel capability. Rather than transmitting its signal on
one frequency only, the integrated transmitter enables the signal
to be transmitted on multiple frequency channels. Frequency hopping
maximizes the reliability of car keys in environments suffering
from RF jamming. Contrary to conventional devices, the NCF2960 also
features stabilized output power in order to minimize the impact of
varying battery voltage and temperatures.

The basic transponder operation is compatible
with the company’s HT3, HT-AES, and HT-Pro2. Custom
transponder functions can be implemented using the ROM library of
the device by the application. Other key features include 16KB
flash for user application, 1KB RAM, a current source option for
direct LED drive, a temperature sensor, and single lithium cell
operations 2.1 to 3.6 V. It also accommodates up to eight command
button. Wettable package flanks allow optical soldering inspection
without an x-ray,(Contact company for pricing and availability)
